A D.C. Human Services Department employe who was suspended briefly without pay in March after writing to the mayor and other officials letters that were critical of his office won an appeal and recently received reimbursement for the days he was suspended.

And, undaunted by the circumstances that led to the suspension, Benjamin H. Johnson III is still writing the mayor -- this time to voice concern over the entire D.C. government and what he calls the mayor's "irresponsible" leadership.

"The irresponsible behavior of you and members of your administration have verified what many people had already believed -- that home rule would be excessively expensive, regretful, and an embarrassing experience," Johnson said in a letter to Mayor Marion Barry two months after Johnson was suspended.

Johnson, a worker with Human Services' Income Maintenance Administration, was suspended for letters written in June 1985 saying that his office "continues to allow employers to work part time for full-time pay."

He complained about colleagues who were excessively late, who used office telephones for personal calls, played radios, read newspapers and even took naps on the job.

An investigation later said the allegations were unsubstantiated. The person who was tardy, for example, had permission to be late to allow for child care arrangements. And the person taking naps was allowed to do so because she was pregnant.

"Mr. Johnson should present proof or, if he's so unhappy, should go work someplace else," Audrey Rowe, the commissioner of social services who suspended Johnson, said in March.

But Johnson said recently that the decision to reimburse him nearly $700 for the eight working days he was suspended proves that "the information they were using against me {in the suspension} was false."

Johnson said that he is still being harassed by fellow employes but that "it hasn't fazed me in the least." He said he will continue to point out the city's problems until something is done.
